Description
Welcome
- Yes, I'm using a binary release within 2 latest major releases. Only such installations are supported.
- Yes, I've searched similar issues on GitHub and didn't find any.
- Yes, I've included all information below (version, config, etc).
- Yes, I've tried with the standalone linter if available. (https://golangci-lint.run/usage/linters/)
Description of the problem
I went into a panic with a piece of code that converts a slice into an array pointer (using an intermediate named type).
Note that the use of a named type is necessary to reproduce the bug.
